To @ZZ whom it may concern,.-

Be it known that I, GEORGE M. Hons, a citizen of the United States,residing at Evans ville, in the State of Indiana, have invented certainnew an d useful Improvements in Skeleton Arches for Support of ElectricVires, of which the following is a description.

This invention consists of a system of trussing to be used in connectionwith any skeleton arch for support of electric light or lights. Thepurpose of this trussing is to prevent the sagging or settling of thearch, and also, by combining certain of the tie or straining rods withcross-truss H, as shown by the annexed drawings, to hold said archfirmly in place on its supports. In connection with a system ofcrosstrussing, as shown by Figures 2 and 3, any tendency to swaylaterally is prevented.

Fig. l is a front view showing a portion of an arch with the inventionapplied thereto. Figs. 2 and 3 show a system of cross-trussing toprevent lateral swaying.

(No model.)

B are posts for support of the arch. D is a side of the arch bolted tothe posts at K. A and C are tie-rods to prevent sagging, whereof thetie-rod A, being secured to the sidesof the arch at E, passes over theends of crosstie H, is secured at its lower end to the post B, andsecures the arch against any tendency to sway on the post. L L are woodgrounds bolted to the sides of the posts at the top, in order thatsufficient width may be obtained for the arch at the spring thereof. Pis a lamp secured to the top of the arch.

Vhat I claim as my invention is- Ihe combination, with the arch and theposts, of the truss-rods A and C, secured to the sides of the arch, andarranged as shown in Figs. 1 and 3 of the annexed drawings, and asdescribed hereinbefore in this specification.
